Re: [Haskell-cafe] Re: How to generalize executing a series of commands, based on a list?

Thanks very much for the url; helpful site. I got mapM to do what I wanted (first time I've used it); cool function; now I understand it. At your note for mapM I noticed (mapM print); I've been using (show [list]) so much, (mapM print) will be nice for formatting while debugging, etc. Thanks again! -- Peter On Thu, Nov 18, 2010 at 3:44 PM, Henk-Jan van Tuyl wrote:

I'm new to sequence, mapM, and mapM_; I've seen mapM a lot while reading code and wanted to learn it; now I have a reason! Thanks. -- Peter
